[vtkusers] vtkStringArray with heterogeneous number of components?

[David Gobbi]

Hi Simon,

You can do this with a vtkVariantArray, because a vtkVariantArray is
an array of "anything" so it allows you to store a vtkStringArray for
each of your points. It wouldn't be very efficient, however.

My recommendation would be to just use a vtkStringArray and then
use some kind of string delimiter like ";" or ",", for example if the string
is "one;two" you would write your own code to interpret that as multiple
values.
